DETROIT (AP) -- The National Highway Traffic Safety Administration has closed an investigation into engine stalling in some Chrysler cars after the company extended the fuel tank warranty.
The probe covered nearly 154,000 Chrysler 300, Dodge Charger and Dodge Magnum cars from 2006. The cars have 5.7-liter or 6.1-liter V8 engines.
Investigators checked more than 1,200 complaints and found 299 in which the fuel system allowed gas tanks to be over-filled. That caused the cars to stall when stopped or at low speeds.
The problem was traced to a fuel shut-off device that can stick open when exposed to high-ethanol gasoline. Chrysler updated the part in new cars and guaranteed it for life in cars now on the road.
The agency said Friday that the problem is a low risk to safety.
